Step by step: None
Answer:
5 amperes will produce the maximum power
Step-by-step explanation:
The power generated by an electrical circuit (in watts) as a function of its current c (in amperes) is modeled by: P(c)= -12c^2 + 120c.
To find out the maximum power we need to find the vertex
formula to find x -coordinate of vertex is 
P(c)= -12c^2 + 120c is given in the form of y=ax^2+bx+c
a= -12, b = 120

c= 5 amperes will produce the maximum power
2 + 65 + 7 × 3
= 2 + 65 + 21
= 67 + 21
= 88
answer is 88
47 square units is the answer on edge
Prime numbers: 2, 3, 5, 7.
There are 4 prime numbers and 10 possibilities, so the probability is 4/10 = 2/5 or 40%
